For this report, we explored the impact of increased electrification on homes with smaller electric panels (100A). We examined second-by-second data from our research network in over 400 homes over the last three years. We scanned more than 12.6 billion data points and analyzed all main breaker loads that exceeded 20kW – a level that would require a 100A main breaker upgrade if the home load is continuous. By studying the home loads and use patterns above this power draw, we can gain insight into the residential load patterns that will drive electric panel replacement over the coming decades.
